Replace data source name in template

[tmor]

Summary

Hello,
I used the template/variable feature and the data source names were saved.

• Variables | Grafana Labs

This changes works for me.

Environments

• Grafana 7.0.6
• jq 1.6
• Ubuntu 18.04 LTS on WSL1

Steps to reproduce

Example dashboard: templating-grafana7.0.6.zip

...
    "templating": {
      "list": [
        {
          "current": {
            "selected": true,
            "text": "CloudWatch(old)",
            "value": "CloudWatch(old)"
          },
...

Command:

jq -Mf ./update-datasource.jq --arg old "CloudWatch(old)" --arg new "CloudWatch(new)" < templating-grafana7.0.6.json | jq .dashboard.templating

"current" appears other part of the json. It needs some qualifier to avoid unintentional replacing.
